1995 mar 21 7 philips semiconductors product speci?cation audio fm processor for vhs hi-? audio TDA9610h functional description the ic is intended for use within the audio fm system of vhs video recorders. three modes of operation can be distinguished: record mode playback mode loop-through mode. switching and control of the three modes is done by the i 2 c-bus. record mode the audio signal, selected from the four stereo audio inputs (ext1l, ext1r, ext2l, ext2r, cinl, cinr, tunl and tunr), is fed to the volume control stage (separate for left [l] and right [r]). the information for linout is, after summing of l and r, derived from either one of the four stereo inputs or the volume control output or one of the mono inputs (exn1 and exn2). after the low-pass filter (lpf) and signal compression in the noise reduction (nr) and filter block the audio signal is available at afoutl and afoutr. the compressed signal is now fm modulated on a rf carrier in the pll block. after low-pass filtering and summation of both rf carriers (l and r) the signal is available at fmout. the output select block offers the possibility to choose eight different audio signal modes: 1. stereo. 2. left. 3. right. 4. mono. 5. normal. 6. mixed stereo (stereo + linin). 7. mixed left (left + linin). 8. mixed right (right + linin). these audio signal modes are selectable for the output stages linel, liner and modout. the standard audio output is linel and liner, e.g. for scart output. modout is a mono audio output, with an overload-protecting agc, to drive an external rf modulator. the headphone select block offers the possibility to choose either the output select signal or four independent audio signal modes (stereo, left, right and normal) for the output stages hpoutl and hpoutr. hpoutl and hpoutr, with common volume control for l and r, is suitable for direct headphone drive. dcoutl and dcoutr are intended for vu meter drive. it is connected to the selected stereo audio input after the volume control block. the output signal at dcoutl and dcoutr is proportional to the square root of the recorded audio signal (see fig.3). playback mode the two fm modulated rf carriers, present at the two fminl and fminr inputs after being band-pass filtered, are demodulated in the pll block. the lf audio signal is fed through a sample-and-hold circuit to suppress head-switching noise. the demodulated audio signal is available at afoutl and afoutr. the audio signal is low-pass filtered and expanded in the noise reduction (nr) and filter block. the resulting audio signal is available after the output and headphone select blocks for all four output stages (linel, liner, modout, hpoutl, hpoutr, dcoutl and dcoutr). the functionality of the output and headphone select blocks is identical to the record mode. during playback dcoutl and dcoutr are connected to the headphone select block. the functionality of the input and normal select blocks is also identical to record mode (see fig.3), which offers the possibility to control (other) audio signals independently for linout (see fig.4). loop-through mode this mode is similar to the record mode (see fig.3), except for the fmout pin, which is inactive, and the raf output which is active low (see fig.5).

1995 mar 21 38 philips semiconductors product speci?cation audio fm processor for vhs hi-? audio TDA9610h adjustment of vco frequency set the TDA9610h in record mode (ntsc off), no audio input signal. measure the frequency at fmout (pin 56) with a frequency counter and use the vco test modes (see section function byte) to output only the channel of interest. adjust the vco frequencies to 1.4 mhz 10 khz and 1.8 mhz 10 khz by means of the potentiometers at pin 64 (fadjl) and pin 53 (fadjr). when ntsc is to be the main video standard, set ntsc on and adjust to 1.3 mhz and 1.7 mhz for optimum frequency accuracy. standard fm deviation and audio level reference levels of frequency deviation and audio output level are set by the resistor value at pin 24 (rvar); simultaneous for left, right, playback and record. typical resistor values can be calculated with equation: where: d f = reference fm deviation. a = reference audio output level (1 khz audio frequency). if adjustment for overall tolerance is needed, r has to be made adjustable for the range 0.7r typ to 1.4r typ . set the TDA9610h in playback. use a hf test generator to make a carrier of 1.4 mhz with the desired modulation and input this signal at fminl (pin 61) or before the band-pass filter and measure the audio output level at linel (pin 27). r typ d f 50 khz ------------------ ? ?? 2 a 400 mv (rms) --------------------------------------- ? ?? ---------------------------------------------- 2.2 k w = power-down mode to lower the dissipation in a stand-by situation, the 12 v supply voltage at pin 19 (v dda1 ) and pin 20 (v ddh ) may be switched off, with pins 19 and 20 floating. no low-ohmic dc path to ground may be seen from pins 19 and 20, because this will drain extra current from the 5 v supply via these pins to ground. because of the fact that the i 2 c circuitry and the digital outputs raf, ntsc and xs are supplied via the 5 v supply, no i 2 c settings will be lost and the output pins can still be used. for instance, xs can be used to drive external mute transistors to mute the dc jump at the line outputs when switching the 12 v supply. raf i/o the status of the i 2 c raf bit is output at pin 14 (raf = high; record). this output can be used to switch the audio fm head amplifier to playback and record. if accurate fast switching of the TDA9610h is needed, this pin can also be used as input. thereby overruling the i 2 c raf bit. to make this possible the raf output is current limited. when using the raf pin as output, no more than 35 m a (low) and 185 m a (high) current may be drawn from this pin to assure the mode of the TDA9610h is not changed. when using the raf pin as input, the voltage source used must be capable of delivering at least 345 m a (forced high; > 3.5 v) or sinking at least 65 m a (forced low; < 1.5 v).

1995 mar 21 40 philips semiconductors product speci?cation audio fm processor for vhs hi-? audio TDA9610h soldering plastic quad ?at-packs b ywave during placement and before soldering, the component must be fixed with a droplet of adhesive. after curing the adhesive, the component can be soldered. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. maximum permissible solder temperature is 260 c, and maximum duration of package immersion in solder bath is 10 s, if allowed to cool to less than 150 c within 6 s. typical dwell time is 4 s at 250 c. a modified wave soldering technique is recommended using two solder waves (dual-wave), in which a turbulent wave with high upward pressure is followed by a smooth laminar wave. using a mildly-activated flux eliminates the need for removal of corrosive residues in most applications. b y solder paste reflow reflow soldering requires the solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the substrate by screen printing, stencilling or pressure-syringe dispensing before device placement. several techniques exist for reflowing; for example, thermal conduction by heated belt, infrared, and vapour-phase reflow. dwell times vary between 50 and 300 s according to method. typical reflow temperatures range from 215 to 250 c. preheating is necessary to dry the paste and evaporate the binding agent. preheating duration: 45 min at 45 c. r epairing soldered joints ( by hand - held soldering iron or pulse - heated solder tool ) fix the component by first soldering two, diagonally opposite, end pins. apply the heating tool to the flat part of the pin only. contact time must be limited to 10 s at up to 300 c. when using proper tools, all other pins can be soldered in one operation within 2 to 5 s at between 270 and 320 c. (pulse-heated soldering is not recommended for so packages.) for pulse-heated solder tool (resistance) soldering of vso packages, solder is applied to the substrate by dipping or by an extra thick tin/lead plating before package placement.
